I don't know why, but I can't find .xession-errors or I don't have such file in
my system.

I think it can, It can deliver 800 watts.
As I mentioned in the other email, I can get 2560x1080 using DVI cable,
but with very very poor quality. Can this all be related to cable?
When I use DVI cable I see thi error on my _monitor_:
The screen is not currently set to the recommended resolution.
A DVI Dual-Link cable is provided.
Other DVI cables may be used, but they must be Dual-Link DVI cables.
Otherwise the video will not display or have poor quality.
